You know you're in trouble when PHK and I agree. One would think a
(double precision) floating point epsilon test might be what you
want. In those cases that demand some sort of archival query, an ISO
8601 string might be appropriate, but one would typically expect
queries to be issued on a window about the desired timestamp, or
perhaps given a range specification "from 10:03:01.933 to
10:03:02.008" (whether a string, integer or floating point - binary
or sexagesimal or BCD for that matter).
